Patent DE-3315909-A1 (DE)
Title: System for width distribution in the filling shaft
Inventor: HERGETH HUBERT DIPL ING
IPC: D01G23/04
Filed: 1983-05-02
Abstract: To avoid fleeces being non-uniform over the width in willows, a system consisting of a width-distribution measuring system, an evaluation unit and a control unit and of a filling shaft is used. The air flow in the filling shaft is influenced according to the measured width-distribution profile in the fleece or in the willow feed. To influence the air flow, air-outlet surfaces extending over the entire working width of the filling shaft are subdivided into portions. The air flowing out in the portions is influenced by sliding plates, flaps or counterpressure. Since the fibre material in the filling shaft is distributed by the air, by influencing the air, the material distribution over the working width of the filling shaft can be controlled and a uniform willow feed thus obtained.

Patent DE-3442374-A1 (DE)
Title: Redundant uninterruptible power-supply system
Inventor: SIEDENBERG JUERGEN
IPC: H02J9/06
Filed: 1984-11-20
Abstract: The redundant power-supply system for railway protection systems consists of two switched-mode power supplies (SN1, SN2) which are connected on the output side and are regulated to predetermined output voltages. The one switched-mode power supply (SN1) receives the output voltage directly as a control variable. The output voltage is supplied as the control variable to the second switched-mode power supply (SN2), after being increased or reduced periodically by predetermined amounts. In consequence, the output voltage of the second switched-mode power supply (SN2) is cyclically less than and more than the value of the output voltage of the first switched-mode power supply (SN1). This has the consequence that the two switched-mode power supplies (SN1, SN2) alternately emit the full amount of the power required for the loads which are connected. Connected to the two switched-mode power supplies (SN1, SN2) are two threshold-value discriminators (SR1, SR2) whose switching thresholds are respectively less than and more than the output voltage of the first switched-mode power supply (SN1) by a predetermined voltage value. The signals which are emitted from the threshold-value discriminators (SR1, SR2) make it possible to identify indirectly whether the two switched-mode power supplies (SN1, SN2) are operating correctly or not. <IMAGE>
